Syntenic analysis of the mitogenome sequences of S. splendens (OQ675154 and OQ675155) in this study and S. splendens (PNBA02000024.1) (A), S. splendens (OQ675154 and OQ675155) and S. miltiorrhiza (B), and S. splendens(OQ675154 and OQ675155) and S. officinalis (C). The mitogenomes of S. splendens (OQ675154 and OQ675155), S. splendens (PNBA02000024.1), S. miltiorrhiza, and S. officinalis are shown with orange, red, green, and blue bars, respectively. Regions that have an identity score of more than 85% are connected with grey arcs.
